The sunroof on my 2005 C2 S is struggling to open/close properly because (I think) the lubrication on the spiral cables is old and gummed up. I would like to remove the cables so that I can clean and re-lubricate them. Can anyone advise the easiest way to do this? I'm really hoping someone knows how to do this without having to remove the headlining and frame etc.

Good evening everyone,
I'm new at using forums so excuse me if I am not posting in the correct location but I really need some advice and assistance.
I live just outside of Waco, TX and last Thursday as I was driving my son to school down I-35 we hear a loud boom, almost like a gun went off. My son looks up and see and hears the glass has broken on the sunroof (not the entire panaoramic just the front part). There were no cars around us, nothing hit us nor did we hit the sunroof from within, it basically self exploded like it was under immense pressure as the glass went up instead of down. Thankfully the suncreen netting caught some of the glass but there was damage to the body/paint on the rear section of the roof. I was warm in our garage 75 degrees +/- but the outside temps were low 40's high 30's that morning then the sun came out in force so not sure that had anything to do with it, cabin pressure, etc. Now here is the issue. I call Park Place Porsche in Dallas where we bought our last 3 Cayenne's they send a tow truck to pick it up that morning, do not hear from them until 7pm tonight and I am not happy. They are telling me since their service tech manager cannot figure out how this happened they will not warranty it....REALLY? So they can deny warranty because they can't explain it? Now I am set to call and talk to the service manager and/or the head of the dealership because I'm not buying it, I've done my research over the weekend and this has become a big issue with sunroofs over the years and it's not an unknown thing (even though they are playing dumb). What can I do?

Hi, i apologise for being a lurker and not really ever posting since i joined; but i have a serious issue right now :^(
ive been DIYing most stuff for my car
- pioneer nav
- footwell lighting
- seatbelt replacement
- o2 sensor replacement
etc etc.
but this has me absolutely stumped.
a few weeks ago the interior trim / lining of the sun roof came off while the sun roof was open. it basically got stuck above the headliner in the car; so after i closed the sunroof, i wasnt able to ever open it fully again. i tried to tackle this problem today and one problem led to another and this whole sunroof thing has me so frustrated.
Basically where it stands now is; ive removed the entire ceiling of the car - center consol, headliner, sunroof, sunroof interior trim, motor, rails.. EVERYTHING,
the reason for this was because after i unscrewed the sunroof pannel and removed it, the sunroof rails were not doing anything when i pressed buttons. i though there was something stuck in the tracks at first, but couldnt find anything. then i took out the motor to see wht was up and realized that the close button doesnt work but the vent button and the sunroof forward button do. they only turn the gears a few rotations before stopping. obviously because my roof is in the most extended positon (open) the motor only clicks and doesnt do anything when i press buttons; so i removed the motor to find that it can only rotate in one direction.
what do i do??? i think its the **** programed circuit (the one with the NEC chip on it) thats got the problem. Any way to reset it; or to let the circuit know that the sunroof is already in the vent position and it needs to stop trying to make it vent more?
p.s i broke the mechanism that lets me manually crank the sunroof lol. so thats not an option.
ahhhhhhhhhhhhh!!!! any help is appreciated, or even a service manual that tells me how the hell i re-build the sunroof.
p.p.s my possible diagnostics:
something stuck in tracks
the computer that tells the sunroof what to do is wonky
the close button is broken
motor for some reason only turns one way
pleaase help with solutions, or a service manual to show me what to do :(

1999 C4, which I've owned and enjoyed for 7 years, since 38K miles (now 159K miles).
This evening the sliding sunroof was sliding open nicely. It only slides open if I hold down the button. But then a slight bit of rough road, at 35 mph caused it to hick-up a bit (clicking noises). And I probably briefly pushed the wrong button(s). Now it's wide open (slid all the way back, i.e. roof open to the sky). It will only shut about one inch, then stops. And repeated attempts make it close back up only result in opening back up that one inch. The tracks look clean, and were last lubricated 2 years ago. I don't use the sunroof much, other than the slight tilt up to vent.
Suggestions on how to get it to close, and how to fix it?
Manual close doesn't work -- can't get the supplied wrench to close it, because it's too hard to turn, and I don't want to force it, and goof something up further.
I don't see any thread here that addresses this stuck open issue, and re-teaching in this circumstance doesn't seem to work (I tried it).
I appreciate your suggestions and wisdom.

I have read all the articles on sunroof woes, but I still have some questions.
Car: 2002 996 C2
Problem: one touch open not working, need to hold down switch and even then does not always want to close, slows down midway closing, generally seems slow
What I have done:
Cleaned the rails and tracks
Put some light lube on various surfaces (Silicone on the surfaces, light oil on the cables)
Disconnected the battery & retrained the sunroof -- which worked for one cycle
Opened the gear box and relubed with lubriplate (be careful, the gears and small spring will fall out)
Ran all this with a battery charger connected so as give full power to the motor
All to no avail.
Question:
Is this likely to be an issue with the motor wearing out? It free wheeled fine with the gears removed.
Or is there too much build up of internal friction with the cable mechanism? More lube and if so which?
Is there a way to diagnose this before I start spending $$ on parts and labor?
Thanks

For a little while now, my passenger side window
has not been dropping down to allow the door to open/close. So I bought the
microswitch and went to install it on saturday. Well, it wasn't until after I
had the door panel off that I realized I don't have the triple square bit to
remove the latch assembly NO worries,
I'll put it back together and do the fix after I pick up the correct tool.
So after the door panel is back together, I fire it up and notice:
1-
the power windows don't work
2- sunroof doesn't work
3- rear defroster
doesn't work
4- map lights don't work.
Now, what would pulling the
door panel off and putting it back on have ANYTHING to do with this list of
failures? I checked the associated fuses in block D of the fuse box. They were
all fine. Is there a relay connecting all of these features that may have
failed?
One other thing that I can't imagine would have an impact: When I
went to remove the door panel, the wires that go to the little orange LED in the
handle pulled out of the connector. I plan on picking up some wiring supplies at
radioshack to fix this, but its only the handle LED...if that is somehow wired
in series with the rest of those features...I would have to question Porsche's
sense in that.
Anyone know what might be going on here? Also, does
anyone have a wiring diagram of this car?
Thanks,
Connor
